摘要
对现有的适合于大容量滤波场合的并联混合有源滤波器原理进行了分析。在控制方法上对并联型有源滤波器进行了改进 ,并在理论上对其性能进行了分析。分析结果表明 ,这种混合有源电力滤波器可进一步抑制谐波 。
Through analyzing the principle of a parallel hybrid active power filter (HAPF) which is currently suitable for filtering high power harmonic source , a new con trol approach is proposed . And the filtering performance of the HAPF adopting n ew control approach is also analyzed theoretically . The results indicate that t he harmonics can be suppressed further by this kind of HAPF, and the resonance b etween reactive filter and system impedance can be eliminated completely .
